Eh??? Which point? You didn't tell us any, except for your circular ranting.

Oh noes, not more pink elephants...

Because maintaining your own profiles and stacking them and dealing with
all the related mess is a _lot_ easier that sticking a + before foo in
IUSE. Right. ;)

You are really circular, fix your record player :P

Defaults that makes sense in profiles can and will stay there and
noone's damn forcing you to change it. We are talking about per-package
(or per-ebuild even) stuff here, which is a feature that has been
missing for ages. Just search for all the bugzilla bugs where it would
make sense but it can't be done without bloating the profiles'
make.defaults with ebuild-specific mess, inventing redundant use flags
so that other ebuilds don't pull in unwanted dependencies, check all the
no* flags that exist just because of this missing feature.

Sigh...
